Engineering Contradiction Analysis
1Reliability
If the physical quantum chip executes one quantum task at a time to avoid errors, then the reliability of quantum computation is improved, but the productivity of the quantum chip deteriorates
Solution Approach 1:
The patent divides a physical quantum chip into multiple virtual quantum chips, where each virtual quantum chip corresponds to a subset of physical qubits. This segmentation allows multiple quantum tasks to be executed simultaneously on different virtual quantum chips using the same physical hardware, thereby improving productivity while maintaining reliability through isolated execution environments.
2Stability of the object's composition
If the physical quantum chip is dedicated to a single quantum task, then the stability of quantum states is improved, but the adaptability of the quantum chip deteriorates
Solution Approach 1:
The patent enables a single physical quantum chip to serve multiple functions by creating virtual quantum chips that can independently execute different quantum tasks. The physical chip maintains stability for each task while adapting to various quantum computations through the virtualization layer, which maps different logical quantum circuits to appropriate subsets of physical qubits.
3Productivity
If multiple virtual quantum chips are created from a single physical quantum chip, then the productivity of quantum computation is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a virtual quantum chip as an intermediary layer between the physical quantum chip and quantum tasks. This virtualization layer manages the mapping between logical quantum circuits and physical qubits, handling the complexity of resource allocation and task scheduling while presenting simplified interfaces to users executing quantum computations.
